Spinal cord injuries as a consequence of falls: are there differential rehabilitation outcomes?

Pathophysiology of Spinal Cord Injury and Tissue Engineering Approach for Its Neuronal Regeneration: Current Status and Future Prospects

A spinal cord injury (SCI) is a very debilitating condition causing loss of sensory and motor function as well as multiple organ failures. Current therapeutic options like surgery and pharmacotherapy show positive results but are incapable of providing a complete cure for chronic SCI symptoms. Tissue engineering, including neuroprotective or growth factors, stem cells, and biomaterial scaffolds, grabs attention because of their potential for regeneration and ability to bridge the gap in the injured spinal cord (SC). Preclinical studies with tissue engineering showed functional recovery and neurorestorative effects. Few clinical trials show the safety and efficacy of the tissue engineering approach. However, more studies should be carried out for potential treatment modalities. In this review, we summarize the pathophysiology of SCI and its current treatment modalities, including surgical, pharmacological, and tissue engineering approaches following SCI in preclinical and clinical phases.

The influence of psychological need on rehabilitation outcomes for people with spinal cord injury

STUDY DESIGN

Single-centre, retrospective study of people with a spinal cord injury or disorder (PwSCI/D) and identified psychological need.

OBJECTIVES

To examine the effect of psychological need on rehabilitation outcomes.

SETTING

National Spinal Injuries Centre (NSIC), Stoke Mandeville Hospital, Buckinghamshire Healthcare NHS Trust, United Kingdom.

METHODS

Self-reported data from the Stoke Mandeville Spinal Needs Assessment Checklist (SMS-NAC) were used to examine identified psychological need (characterised by referral for psychological treatment, or scoring above clinical threshold in admission psychometric measures) on SCI rehabilitation outcome domains. Participants were grouped according to whether they were referred, not referred, scored above or below clinical threshold.

RESULTS

234 participants were included (Mean age at injury (years) = 53, 70% Male, 29% tetraplegia, 38% paraplegia, 33% ASIA D). There was a significant improvement in outcome scores from admission to discharge across all domains irrespective of participant group, however individuals with identified psychological need scored lower across all rehabilitation domains than those without. While individuals with psychological need demonstrated longer rehabilitation stays, more frequent and longer discharge delays, they also showed comparatively greater rehabilitation improvements. Psychological screening measures were more effective at detecting psychological need than individuals identified via referral, and participants scoring above clinical threshold had poorest overall rehabilitation outcomes.

CONCLUSIONS

Individuals with psychological need have greater rehabilitation need and may require longer rehabilitation and benefit from additional discharge planning. Early, proactive psychometric screening can better facilitate improvements for delivering rehabilitation. Future research should consider specific contributing factors to psychological need, such as pre-existing mental health conditions or socio-demographic influences.

Epidemiology of traumatic spinal cord injury in Finland

Study design

Prospective cohort study.

Objectives

To determine the incidence and evaluate the characteristics of newly injured patients admitted to two spinal cord injury (SCI) centers during a 4-year period.

Setting

Oulu and Tampere University Hospital, Finland.

Methods

A dedicated multidisciplinary team evaluated all of the patients with new traumatic SCI (TSCI). The data were recorded according to the International Spinal Cord Injury Core Data Sets.

Results

In a 4-year period, 346 new patients with TSCI were admitted to the study centers. In the Oulu and Tampere University Hospitals’ catchment areas, the mean annual incidence of TSCI was 36.6 per million. The leading causes of injury were low-level falls (36.2%), high-level falls (25.5%), and transport-related accidents (19.2%). In the patients >60 years, 72.6% were injured by falling and the proportion of low-level falls was 49.7%. In the patients ≤60 years old, 47.4% were alcohol-related. The proportion of cervical injuries in the patients >60 years was 77.1%, while in the patients ≤60 years the proportion was 59.6%. The incidence of TSCI was higher during the Summer and Autumn months.

Conclusion

The mean annual incidence of TSCI was 36.6 per million corresponding to 200 new annual cases in Finland. Incomplete tetraplegia due to falling among elderly was overrepresented in the study population. Alcohol-consumption preceded injury in nearly half of the cases in the younger population. The prevention should focus on alcohol-related injuries and falls in the elderly.

Fall-induced spinal cord injury: External causes and implications for prevention

OBJECTIVE

To document the demographic and clinical profile of persons who sustained spinal cord injury (SCI) as a result of accidental falls and to determine the usual circumstances surrounding the fall-induced SCI.

DESIGN

Cohort study.

SETTING

21 SCI Model Systems centers throughout the United States.

PARTICIPANTS

6,408 individuals with traumatic SCI between 2005 and 2014 were recruited from the National SCI Database. 1,877 (29%) of them were injuries caused by falls.

INTERVENTIONS

Not applicable.

OUTCOMES MEASURES

External causes of injury documented by the International Classification of Diseases, 10(th) revision, Clinical Modification (ICD-10-CM).

RESULTS

Falls on the same level from slipping, tripping, and stumbling were the most common cause of fall-induced SCI (20%), followed by falls from building (16%), stairs and steps (16%), and ladder (9%). People who were 61 years of age and older had the highest frequency of falls on the same level, while those aged 16-45 years had a higher percentage of falls from buildings, usually work-related. The mechanisms of falls also varied by sex and race. Associated injury and vertebral injury occurred frequently among falls from buildings and ladders. High falls were more likely to be work-related and result in thoracic and complete injury, while low falls were more commonly associated with cervical and motor functionally incomplete injury.

CONCLUSION

The study findings of different mechanisms of falls by age, sex, race and medical consequences provide an insight for future interventions aimed at high risk persons, activities, and environmental factors for preventing or reducing fall-induced SCI.
